A method of reading pixel data from a pixel array includes exposing each one of a plurality of regions of pixels a respective exposure time. Pixel data is read from the plurality of regions of pixels. The pixel data is interpolated from a first one of the plurality of regions of pixels to determine the pixel data of the regions of pixels other than the first one of the plurality of regions of pixels to generate a first image having the first exposure time. The pixel data is interpolated from the second one of the plurality of regions of pixels to determine the pixel data of the regions of pixels other than the second one of the plurality of regions to generate a second image having the second exposure time. The images are combined to produce a high dynamic range image.
